Kubbi serves as a secure handoff layer specifically designed for AI agents, facilitating the secure transmission of data, files, and execution results among various systems, agents, or individuals via temporary, encrypted claim links. Rather than transmitting sensitive information directly through workflows, prompts, or logs, kubbi empowers a producer to generate a payload that encapsulates content or packaged files, assigns a time-to-live, and creates a unique claim URL for sharing with the next participant in the workflow. The recipient can then access the payload at their convenience, with the option for the data to either automatically expire or be permanently deleted according to predefined retrieval limits. This methodology significantly minimizes the risk of sensitive data exposure across systems and inhibits any unintentional logging, caching, or replaying of that information. Furthermore, kubbi is versatile, accommodating various use cases like the transfer of configuration files, datasets, reports, tokens, and any other transient or sensitive data that should not persist within systems. By implementing such a secure transfer process, kubbi enhances data integrity and confidentiality throughout the entire workflow.
